Application filed August 24, 1909. Serial No. 514,404.

To all whom it may concern:

Be it known that I, FREDERICK W. SIM- SON, a citizen of the UnitedStates of America, and a resident of Winthrop, in the county of Sufiolkand State of Massachusetts, have invented certain new and usefulImprovements in Car-Ventilators, of which the following is aspecification.

This invention relates to car ventilators and has for its object theprovision of a ventilator which may be permanently installed in theframework thereof intermediate the windows and which may be readilyregulated by any passenger adjacent to the ventilator.

The invention consists in two tubular members which are adapted totelescope into each other and be fixedly secured in adjusted position,the inner member being provided with a screen extending transversely ofthe bore thereof to prevent cinders from coming into the interior of thecar while between this screen and the outer end of the ventilator is apivoted damper which may be operated by a suitable mechanism extendinginto the car interior.

The invention consists further in certain novel features of constructionand arrangement of parts which will be readily understood by referenceto the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a vertical section through aventilator, embodying the features of this invention. Fig. 2 representsa horizontal section of the same, the cutting plane being on line 22 onFig. 1. Fig. 3 represents a transverse section of the tubular members,the cutting plane being on line 3-3 on Fig. 2, looking in the directionof the arrow, and Fig. 4 represents a transverse section of the same,the cutting plane being on line 44 on Fig. 2, looking in the directionof the arrow.

Similar characters designate like parts throughout the several figuresof the drawin s.

Tn the drawings, 10 and 11 represent, respectively, the outer and innerportions of the car frame interposed between two car windows. Thesemembers 10 and 11 have openings cut therethrough in axial alinement inwhich are positioned the flaring ends 1213 of the outer and innertubular members 14 and 15. The cylindrical portion of the tubular member15 is adapted to enter the bore of the cylindrical portion of thetubular member 14 and when properly adjusted therein with the beads 16and 17 formed upon the outer edges of the flaring conical ends 12 and 13registering against the outer walls of the members 10 and 11. Thesemembers are secured in position so that they cannot turn by means ofsecuring devices such as screws 18.

Fixedly secured in the cylindrical portion of the tubular member 15 is ascreen 19 between which and the outer end of said cylindrical portion ofthe tubular member 15 is a pivoted damper 20, the pivot member 21 ofwhich extends downwardly through a hub formed upon or secured to thecylindrical portion of the tubular member 15. The lower end of this ivotmember 21 has secured thereto a mem er 23 which is connected by a link24 to another arm 25 pivoted to a stud 26 formed upon or secured to themember 15.

Radiating from the stud 26 and formed integral with the arm 25 is anoperating handle 27, the inner knobbed end of which extends into theinterior of the car through an opening 29 formed in the flaring end 13of the tubular member 15. It is obvious from an inspection of thedrawings that a movement of the handle 27 from one end of the slot 29 tothe other will close or open the damper 20, as desired, while anintermediate position between the two ends will permit a partial closingof said damper.

Extending diametrically across the flaring conical end 12 of the tubularmember 14 is a deflector plate 30 normally vertical when in operativeposit-ion, this deflector plate preferably extending beyond the outerface of the exterior wall 10 of the car frame. When the car is moving inthe direction of the arrow as the deflector plate 30 will cause the airstriking against the front face thereof to be deflected in the directionof the arrows b into the interior of the car when the damper 20 isopened, as indicated in Fig. 2 of the drawing.

Any cinders which may be deflected into theventilator will be preventedfrom passing into the interior of the car by means of the screen 19.When the damper 20 is in open position, as indicated in the drawings,the edge thereof substantially registers with the inner edge of thedeflector plate 30, as indicated in Fig. 1 of the drawings.

Interposed between the screen 19 and the edge of the damper 20, when inopen position, is a radial member 31 normally vertical and extendingupwardly from the inner wall of the member 15, this radial member 31,damper 20, and deflector 30 all being in alinement when the damper 20 isin open position. This radial member 31 is provided on either side withflaring wings 32 which are adapted to deflect the heavier cinders whichmay enter the bore of the ventilator and cause them to be carriedupwardly around the damper 20 and out upon the opposite side of thedeflector plate 30. The inner end of the radial member or partition 31is slightly removed from the screen 19 to permit any of the cylinders topass around this end of the partition.

Just inside of the screen 19, the member 15 has mounted a revoluble ring33 provided with a diametral member 3a to which is hinged in anywell-known manner a deflector plate 35. The hinge between this plate 35and the diametral member 3 1 has sufficient friction to cause thedeflector plate 35 to retain any angular position relative to therevoluble ring 33 in which it may be placed by the passenger. It isobvious therefore that by the manipulation of this deflector plate 35about its hinge connection with the ring 33 and by means of the rotationof the ring with the tubular member 15 the air passing through theventilator may be deflected at the will of the passenger adjacentthereto. This provides a permanent fixture which is always in positionfor the passenger to operate as he may desire to secure the ventilationwhich he himself desires without disturbing others adjacent to him, andit also provides a means whereby the air thus admitted may be deflectedas he may wish. It dispenses with the necessity of calling the portersto provide the usual ventilators which are adjusted in the window frame.

It is believed that the many advantages of this invention and itsoperation will be fully apparent without any further descriptlon.

Having thus described my invention, I claim:
